SF6 Potential Transformer
SF6 voltage transformer adopts SF6 gas with excellent insulation property, the working pressure is generally among 0.3~0.35MPa, and fibrous insulation material is not allowed to use in SF6, so insulation between windings adopts Mylar. To improve electric field, intermediate electrode is installed among primary winding and there are electrodes screen between iron core and winding.
